Support for the Wahoo RFLKT+ Barometric Altimeter data

As of June 2016, the Strava app for iPhone no longer supports direct connection with the RFLKT device for recording. However, you can instead record with the Wahoo Fitness app and set up the automatic sync from Wahoo to Strava.

One outstanding request is for Strava to recognize the elevation data supplied by the RFLKT+'s barometric altimeter.

I'm working to determine IF the Wahoo Fitness app is able to supply the correct elevation data and device tags for Strava to read and recognize the elevation.

For those of you with this device, can you reply here with how you use the device and how you upload your data to Strava? Also, please include example activity URLS where elevation was not recognized by Strava (and instead recalculated)

I use the Wahoo app to record the ride on an iPhone 6. After saving the ride, I use the "Share" feature to upload it to Strava. There's an option to email the data and it gives me all the various file formats I could want, but I have no idea what format is used when sharing directly w/ Strava using my Strava ID and password.

I took a test ride and uploaded it to Strava via the Wahoo app share button.

On Strava, it shows that the device is a Wahoo RFLKT+. All I really see is an elevation of 253 ft. I can look at the graph, but the scale is 0-800 ft and the max elevation is 337, so there's not enough scale to see the up's & down's when it varies between 200-350 ft. Looking a the Wahoo app ride history, it shows a total climb of 130 ft with a start elevation of 206 ft.

I don't have a ride prior to Feb w/ the Wahoo app, as I didn't get the Blue SC & RFLKT+ until March.

I find it very interesting that my elevation data is very different based on the site I look at.

I recorded the ride on an iPhone 6+ using the Wahoo Fitness app v5.7.7 (20160312.1) and a Wahoo Blue SC for distance/cadence data and the Wahoo RFLKT+ for displaying the data.

My most recent ride, Wahoo Fitness says I started at 299 ft and had a total climb of 526 ft. Total distance was 28.31 mi with an average speed of 14.68 and w/ a max speed of 26.56 mph. Average cadence was 62 RPM w/ a max of 96 RPM.

I used the "Share" feature to quickly upload/share the ride w/ Strava, Ride With GPS and MapMyRide.

Looking at the Strava app v4.17.0 (4119), Strava shows 28.2 miles ridden, 634 ft elevation gain, and 15.3 avg speed with a max of 26.2 mph. I can't find the cadence info in the app.

Looking at Strava via the web, it shows the same data as the app, but has an average cadence of 47 and a max of 107 RPMs and says the device is a Wahoo RFLKT+.

Looking at Ride With GPS app, it shows 28.2 mi ridden, 757.4 ft elevation gain, 147. mph average & a max speed of 26.1 mph. Average cadence was 59.6 with a max of 107 RPMs.

Looking at Ride With GPS via the web, I can't find the total elevation gain, just a +743 / -725. It shows 14.8 mph average & a mox of 26.1 mph. Average cadence was 59.8 with a mox of 107 RPMs. Seems like the averages are different from the app.

I haven't had any problems, but stumbled upon this thread where Elle asks how we use the device. I own a RFLKT (not a plus), so I don't have a barometric sensor in the device and use the one in my phone instead. I record using Locus Map, which connects to RFLKT using an addon I wrote, and is then able to upload the data to Strava including correct barometric altitudes. This works okay and I'm not having any problems.

Unfortunately communication with Wahoo has been problematic. I had a few questions during the development of the Locus-RFLKT addon and I haven't received a single answer from them. It seems they're not interested in developers making their apps support the RFLKT, and I'm not at all surprised that Strava has dropped the support on both Android and iOS. :-/

But, by the way, I found how convert RFLKT+ altimeters data for Strava from Wahoo app. It isn't simple, but it works well. In Wahoo app you need save workout as FIT file to local storage. After, you need upload FIT to fitfiletools.com, change device to garmin edge 820 for example, and upload to Strava.

May be somebody, who make apps, will doing little automate app for this operations?

Locus does this, it can upload to Strava without having elevation data stripped. Just load the exported file into Locus and export to Strava using Locus. If your phone has a barometric sensor, you might as well just use Locus for both recording and exporting. :-)
